I have the EQ700, it's not bad but, I can't say it's very good either.

The portability is top notch and the sound is so-so (unless you're a basshead) but the build quality is less promising, especially with those thin and fragile looking cables (it seriously looks like I can cut the cables with my fingernails, lol). I used it to listen to classical and orchestral, the sound was quite crisp if not for the lack of padding which inhibits noise reduction from the outside. Overall, the price is right. I saw some from Sony which looked quite similar, don't remember which model.
